I did this many years ago. Yes, each 260 needs to be on its own comm port and you need run a separate instance (tab, window) of Driveware for each. You also have to set up the comm port in driveware that is using the "non-default" comm port every time you open the software. It is very clunky and not the best solution. I would sell your 260s and buy a 481 or 482.

I just tried using a USB hub. I can control a lot of DBX. It works. But it must have a lot of RS serial to USB converter
